Description

Technical Field

[0001] This utility model relates to the field of roller technology, and more specifically, it relates to a toothed roller sleeve and a flat knitting machine roller using the sleeve. Background Technology

[0002] In order to ensure smooth transmission between the sleeve body (cloth sleeve) and the drive rod (roller) and transition rod, the existing high-position roller device of computerized flat knitting machine generally uses the transition rod support to squeeze the end faces of the roller and transition rod to form a tight fit. Therefore, the end faces of the roller and transition rod are subjected to double compression from the sleeve body and the transition rod support, making the overall disassembly and assembly extremely inconvenient. Furthermore, during long-term operation, wear of the sleeve body and slippage between the roller and transition rod can occur, leading to functional failure and affecting production.

[0003] Chinese patent CN212611210U discloses a high-position roller device for a computerized flat knitting machine. The roller has several jacking bearings spaced at intervals between its two ends. Jacking protrusions are provided on the outer surface of the jacking bearings. The lower end of the transition rod support is fitted with corresponding limiting holes along the position of the jacking bearings. An adjustment hole is provided in the middle of the transition rod support along the center of the vertical roller. The adjustment hole is connected to each limiting hole in the same plane. An adjustment rod is provided in the adjustment hole. The jacking protrusions extend into the matching limiting holes, and their upper ends are engaged with the ends of the adjustment rods.

[0004] The aforementioned technical solution first uses a top bearing with a top-moving protrusion and an adjusting rod that abuts against each other to set the tension adjustment force of the roller. The roller, transition rod, and transition rod support are spaced apart to reduce transmission resistance. Based on this, the end faces of the basic roller and transition rod can form a toothed transmission structure with the fabric-holding sleeve. The overall transmission is lightweight, stable, and not easily worn, with a more reasonable structure that is easy to disassemble and adjust. However, in actual use, the fabric-holding sleeve may slide along the length of the roller, thus affecting its normal operation.

[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a toothed roller sleeve and a flat knitting machine roller using the sleeve.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a toothed roller sleeve, comprising a sleeve body, wherein a plurality of driving tooth grooves are uniformly arranged on the inner surface of the sleeve body in a plurality of annular grooves.

[0008] By adopting the above technical solution, driving tooth grooves and annular grooves are alternately arranged on the inner wall of the sleeve. By setting a driving rod with corresponding driving teeth and a limiting ring, the sleeve body is transmitted torque while the circumferential slippage and axial displacement of the sleeve relative to the driving rod are restricted, thereby preventing the sleeve from sliding axially.

[0009] The present invention is further configured such that: the inner surface of the leather body is provided with a plurality of annular protrusions, and two adjacent annular protrusions form a driving tooth groove and an annular groove, and the driving tooth groove and the annular groove are arranged at intervals.

[0010] By adopting the above technical solution, the annular protrusions themselves form a physical barrier, while the grooves (drive tooth grooves / annular grooves) between them are used to accommodate the corresponding structures on the drive rod. This spaced-out protrusion and groove structure provides effective restraint in both the circumferential and axial directions, greatly enhancing the stability of the connection between the sleeve and the drive rod.

[0011] The present invention is further configured such that: the surface of the protruding ring is a convex arc surface, and the bottom of the driving tooth groove and the annular groove is a concave arc surface adapted to the convex arc surface, so that the cross-section of the inner wall of the leather body has a continuous alternating convex and concave arc surface structure.

[0012] By adopting the above technical solution, the matching design of the convex and concave arc surfaces significantly increases the contact area between the inner wall of the sleeve and the outer surface of the drive rod. The continuous convex and concave arc surface structure not only makes the stress distribution more uniform and reduces local wear, but also provides a smooth transition, facilitating the installation of the sleeve body.

[0013] The present invention is further configured such that: a plurality of first tooth plates are arranged in the drive tooth groove along its circumferential direction, a tooth groove is formed between two adjacent first tooth plates, the bottom of the first tooth plate is an arc surface that fits the bottom of the drive tooth groove, the top of the first tooth plate is a flat surface, and its height is lower than the height of the annular protrusion.

[0014] By adopting the above technical solution, the first toothed plate is integrally formed with the sleeve body, ensuring structural strength and smooth force transmission path.

[0015] The present invention is further configured such that: the two side walls of the toothed plate gradually taper from the bottom to the top, forming a symmetrical trapezoidal longitudinal section profile, and the junction of the side wall and the top plane of the toothed plate is a straight edge structure.

[0016] By adopting the above technical solution, it is easier for the first toothed plate to mesh and separate from the corresponding toothed plate, and the difficulty of disassembly and assembly is reduced. The straight edge structure provides clear meshing convenience, thereby reducing slippage.

[0017] A flat knitting machine roller includes a drive rod, a support member, and a split rod disposed within a sleeve body. The surface of the drive rod is provided with a plurality of drive tooth rings embedded in drive tooth grooves and a plurality of positioning rings embedded in annular grooves.

[0018] By adopting the above technical solution, the drive gear ring is embedded in the drive tooth groove of the sleeve to achieve torque transmission, while the positioning ring is embedded in the annular groove of the sleeve to mainly play an axial positioning role. The two work together to ensure that the sleeve does not slip circumferentially or axially during transmission.

[0019] The present invention is further configured such that: the driving gear ring includes a plurality of second gear plates, the top of the second gear plate is an arc surface that fits into a concave arc surface, and its two sides contract from the bottom to the top to form a symmetrical trapezoidal longitudinal section profile.

[0020] By adopting the above technical solution, the arc surface at the top of the second tooth plate matches the concave arc surface at the bottom of the drive tooth groove, increasing the contact area, reducing contact stress, improving wear resistance and transmission smoothness. Its trapezoidal profile matches the tooth groove formed by the first tooth plate of the sleeve, ensuring efficient and reliable meshing transmission.

[0021] The present invention is further configured such that: abutment rings are provided at both ends of the circumferential surface of the drive rod, and an abutment arc surface is provided at the bottom of the support member to cooperate with and abut against the surface of the abutment rings.

[0022] By adopting the above technical solution, the contact arc surfaces are made to contact each other, thereby avoiding contact between the support component and the drive gear ring and positioning ring on the drive rod, which would affect its normal operation.

[0023] This invention has the following advantages: The interlocking of the annular grooves / circular protrusions spaced along the inner wall of the sleeve with the positioning rings / drive gear rings on the drive rod, and the cooperation between the abutment rings at both ends of the drive rod and the abutment arc surfaces of the support members, forms a multi-level axial constraint, thus solving the technical problem of the sleeve sliding along the roller axis.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively. Specific Implementation Example 1:

[0031] like Figure 1 As shown, a toothed roller sleeve includes a sleeve body 1. The inner surface of the sleeve body 1 is uniformly provided with a plurality of drive tooth grooves 2 and a plurality of annular grooves 3. Drive tooth grooves 2 and annular grooves 3 are alternately arranged on the inner wall of the sleeve. Through a drive rod having corresponding drive teeth and a limiting ring, torque is transmitted to the sleeve body 1 while limiting circumferential slippage and axial displacement of the sleeve relative to the drive rod, thereby preventing axial slippage of the sleeve.

[0032] The inner surface of the leather body 1 is provided with several annular protrusions 4, and two adjacent annular protrusions 4 form a driving tooth groove 2 and an annular groove 3, which are spaced apart.

[0033] The annular protrusion 4 itself forms a physical barrier, and the drive tooth groove 2 and annular groove 3 formed between them are used to accommodate the corresponding structure on the drive rod. Through the spaced protrusion and groove structure, effective limiting is formed in both the circumferential and axial directions, which greatly enhances the connection stability between the sleeve body 1 and the drive rod.

[0034] The surface of the annular protrusion 4 is a convex arc surface, and the bottom of the drive tooth groove 2 and the annular groove 3 is a concave arc surface that matches the convex arc surface, so that the cross section of the inner wall of the leather body 1 has a continuous alternating convex and concave arc surface structure.

[0035] The matching design of the convex and concave arc surfaces increases the contact area between the inner wall of the sleeve and the outer surface of the drive rod. The continuous convex and concave arc surface structure not only makes the stress distribution more uniform and reduces local wear, but also provides a smooth transition, which makes it easier to assemble the various parts of the roller and the matching parts with the sleeve body 1.

[0036] A plurality of first tooth plates 5 are arranged along the circumference of the drive tooth groove 2, and a tooth groove is formed between two adjacent first tooth plates 5. The bottom of the first tooth plate 5 is an arc surface that fits the bottom of the drive tooth groove 2, and its top is a flat surface with a height lower than that of the annular protrusion 4. The first tooth plate 5 is integrally formed with the sleeve body 1, which ensures structural strength and smooth force transmission path.

[0037] The two side walls of the first toothed plate 5 gradually narrow from the bottom to the top, forming a symmetrical trapezoidal longitudinal section profile. This creates a trapezoidal tooth groove that is wider at the top and narrower at the bottom between adjacent first toothed plates 5, which facilitates the meshing and separation of the first toothed plate 5 with the corresponding toothed plate. Furthermore, the junction between the side wall and the top plane of the toothed plate is a straight edge structure, which provides a clear meshing boundary and reduces slippage. Specific Implementation Example 2:

[0039] like Figure 2 and Figure 3 As shown, a flat knitting machine roller includes a sleeve body 1 and a drive rod 6, a support member 7 and a split rod 8 disposed in the sleeve body 1. The surface of the drive rod 6 is provided with a plurality of drive tooth rings 9 embedded in the drive tooth groove 2 and a plurality of positioning rings 10 embedded in the annular groove 3.

[0040] The drive gear ring 9 is embedded in the drive gear groove 2 of the sleeve to transmit torque, while the positioning ring 10 is embedded in the annular groove 3 of the sleeve, which mainly serves as an axial positioning function. The two work together to ensure that the sleeve does not slip circumferentially or axially during transmission.

[0041] The drive gear ring 9 includes several second gear plates 11. The top of each second gear plate 11 is an arc surface that fits into a concave arc surface, and its two sides taper from the bottom to the top, forming a symmetrical trapezoidal longitudinal section profile. The arc surface at the top of the second gear plate 11 matches the concave arc surface at the bottom of the drive gear groove 2, increasing the contact area, reducing contact stress, improving wear resistance and transmission smoothness. Its trapezoidal profile matches the tooth groove formed by the first gear plate 5 of the sleeve, ensuring efficient and reliable meshing transmission.

[0042] The drive rod 6 has abutment rings 12 at both ends of its circumferential surface, and the support 7 has an abutment arc surface at its bottom that fits and abuts against the abutment rings 12. This ensures that the abutment arc surface contacts the abutment rings 12, thereby preventing the support 7 from contacting the drive gear ring 9 and the positioning ring 10 on the drive rod, which would affect its normal operation.

[0043] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
